How to Use Autoscale
This is a very useful function for first time users to carry out a simple and quick test
on the input signal. The function is applied to follow-up signals automatically even if
the signals change at any time. Autoscale enables the instrument to set up trigger
mode, voltage division and time scale automatically according to the type, amplitude
and frequency of the signals.
